Tetra 400 air pump

[Myrkk]

Just bought a tetra 400 air pump for my tank, it’s a little bigger than needed but I wanted to split the cables and have multiple small air stones as well as run an egg tumbler from it. Damn that thing is noisy. Tried placing it on a foamy sponge, holding it in the air, putting it on the solid floor… it’s unbearable in a room we are going to use for daily living. Is this normal or do I have a duff one? Anyone any experience of this model, is it just a noisy model? If so I’m sending it back so am on the lookout for suggestions of a quiet air pump to use in a 200l tank. To run the above mentioned things… probably won’t have any eggs to put in the tumbler at this rate though.

I have one . This must be one of those times when being nearly deaf is a mixed blessing because I barely hear it . I like Tetra air pumps . They are very reliable and should you need to replace a diaphragm it’s as simple as simple gets .

I’m about to highjack the thread with a question for Back in the Fold. I have a Boxtech air pump running a sponge in one of my smaller tanks. It stopped working after 13 months. I know nothing about pumps. But I opened the casing and there wasn’t even a hum. No action at all. All the connections were intact. Is it burned out and not fixable? What could be wrong? Or is it just a cheap pump with limited life?

The motor won’t make a sound . Any sound comes from the diaphragm working . Look at your diaphragm very closely . It probably has a crack in it . If not then it’s shot . Some air pumps you can’t even get a replacement diaphragm for . I’ve got a Fusion Quiet Power that’s going in the garbage because of that .

Last one i bought is the Eheim Air Pump 400, and I'm pretty happy with it. you can suspend them and the are pretty silent installed that way.

I had two of those noisy tetra air pumps, they didn't hold up well either.
bought a Fluval Q2 and never looked back. quiet and last long. after 10 years I had to order a set of baffles from amazon and it's still working well and that was 3 years ago.

I don’t think the Fluval Q2 is sold anymore.
